New active photonic components are proposed which exploit two amorphous silicon and related alloys optoelectronic peculiarities. In particular the thermo-optic effect and the photoinduced absorption at the infrared wavelengths are employed to design respectively a spatial switch and a light amplitude modulator. Both devices are integrated within a silicon on SiO/sub 2/ waveguide.
